Research On Disease And Maintenance Technology Of Asphalt Pavement Of Liangwan Expressway

In recent years,with the rapid development of the economy,the demand for expressways is also increasing,and the mileage of expressways is increasing.However,under the influence of heavy traffic and climatic conditions,the asphalt surface of expressways has appeared.Different degrees of disease.With the increasing number of car ownership in China and the increasing trend of heavy-duty traffic,the pressure on the expressway is also growing,and various disease problems on the expressway will follow.Therefore,it is more and more important to take timely and reasonable measures to deal with various diseases on the road,reduce the harm caused by road diseases to driving safety,and maintain the high service capacity of the road.China has a vast territory and different road conditions in different terrains.It is very important to combine the characteristics of regional roads and maintenance and maintenance,scientifically and regularly regulate the maintenance of highways,and effectively improve the benefits brought by maintenance and repair technology in practical application..At present,many highway asphalt pavements in China have not reached the service life,and different degrees of rutting,lateral cracks,longitudinal cracks,cracks,subsidence,pits,looseness,repairs,etc.have appeared to varying degrees,and some road sections even have pavement structures.Sexual diseases,which make the maintenance of asphalt pavement a major research issue facing the road maintenance management department.In view of this problem,this paper takes the asphalt pavement of Liangwan Expressway in Chongqing as an example,and analyzes the types of diseases caused by asphalt pavement and the causes of diseases.According to different types of diseases,this paper analyzes the problem.The technical plan for overhauling typical road asphalt pavement,summarizing the overhaul techniques of different types of diseases and their adaptation,as well as the problems that should be paid attention to during the overhaul of the road surface,in order to be able to provide the actual geological conditions anddamage degree of the highway asphalt pavement in the actual maintenance process.The corresponding methods and experience reference are provided to provide reference for the research on maintenance and repair of highway asphalt pavement,which has strong theoretical and practical significance.
